Combining high-tech HeatGear fabric construction and Under Armour's signature moisture transport system, the HeatGear Solo III Cushion Liner works to wick away moisture and accelerate evaporation so your feet stay cool, dry, and light. Strategic cushioning is built into the sock for maximum shock absorption and protection, while embedded arch support reduces foot fatigue for long-wearing comfort. The HeatGear Solo III Cushion Liner is built from a durable blend of 98% cotton and 2% spandex fabric. Three pairs per pack. Imported.
